A STUDY ON OCCURRENCE CHARACTERISTICS OF MARINE DEBRIS IN THE YELLOW SEA OF KOREA

摘要

The aim of this study knows to occurrence characteristics of marine debris through analysis for change of marine environments and compositions of marine debris. For the distribution and characteristics of marine debris analysis collected in the region of 2000 m~2 on the Daekwang Beach in the Yellow Sea of Korea. In the results of monitoring from 2008 to 2009, the total number of the marine debris was 2,207(Number) in this site. Also analysis for seasonal changes of marine debris used observed value, Topex/Poseidon data concerning tidal current, sea surface wind, and sea surface circulation. Tidal currents appeared that southwest flow in around survey area. Sea wind was the dominant wind of north direction. In addition, sea surface circulation that appeared in form connected with the north wind. This studied results is expected to that change of marine environments affect occurrence of marine debris.
